[utility model content]
The purpose of this utility model is to provide a kind of acoustical generator that can improve the performance of product.
The technical solution of the utility model is as follows: a kind of acoustical generator, it comprises loam cake, lower cover, the basin frame that is provided with receiving space between loam cake and lower cover, be placed in the acoustical generator monomer in the receiving space, described acoustical generator monomer is provided with magnetic circuit system and vibrational system, described magnetic circuit system is provided with the magnetic bowl, described vibrational system is provided with vibrating diaphragm, form ante-chamber between described loam cake and the vibrating diaphragm, described acoustical generator is provided with the side parallel with the vibrating diaphragm direction of vibration, be provided with the louver that is positioned at the acoustical generator side and is communicated with ante-chamber between described loam cake and the basin frame, at least one in the two of described basin frame and loam cake is provided with the first block for the displacement of restriction acoustical generator monomer, and described the first block is arranged in louver.
Preferably, described the first block extends to form to loam cake from the basin frame.
Preferably, be covered with on described extend to the basin frame and with the second block of the first block butt.
Preferably, described the first block is positioned at the periphery of vibrating diaphragm, and extends along the direction of vibration that is parallel to vibrating diaphragm.
Preferably, described the first block has two.
Preferably, described basin has set up inner surface, and described magnetic bowl is provided with sidewall, and described basin sets up the rib that extends to the lower cover direction from inner surface, and described rib is around the sidewall of described magnetic bowl.
The beneficial effects of the utility model are: at least one in the two of described basin frame and loam cake is provided with the first block for the displacement of restriction acoustical generator monomer, described the first block is arranged in louver, because the first block area is little, thereby louver is done more, and then improve the acoustical behavior of product.

Fig. 2 is that Fig. 1 is along the cutaway view of A-A line;
Fig. 3 is the three-dimensional exploded view of the utility model screen acoustical generator.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1 to Figure 3, be acoustical generator 100 of the present utility model, it comprises loam cake 11, lower cover 12, the basin frame 40 that is provided with receiving space between loam cake 11 and lower cover 12, is placed in the acoustical generator monomer in the receiving space.
The voice coil loudspeaker voice coil 22 that acoustical generator monomer involving vibrations system and magnetic circuit system, vibrational system are provided with vibrating diaphragm 21 and are connected with vibrating diaphragm 21, described vibrating diaphragm 21 comprise ball top 211 and the ring section 212 that centers on 211 peripheries, described ball top; Magnetic circuit system comprises magnetic bowl 33, the magnet steel 32 that places magnetic bowl 33 that is fixed on the lower cover 12 and depends on pole piece 31 on the magnet steel 32, simultaneously, 31 of magnetic bowl 33 and magnet steel 32 and pole pieces form magnetic gap, voice coil loudspeaker voice coil 22 is suspended in the magnetic gap, after voice coil loudspeaker voice coil 22 energisings, voice coil loudspeaker voice coil 22 can vibrate under the effect in magnetic circuit system magnetic field, and meanwhile, voice coil loudspeaker voice coil 22 drives vibrating diaphragm 21 and together vibrates.
In the utility model acoustical generator 100, magnetic bowl 33 is provided with the diapire 332 that is connected with lower cover 12 and from diapire 332 vertically extending sidewalls 331, basin frame 40 is provided with inner surface, be provided with the rib 42 that extends to lower cover 12 directions from basin frame 41 inner surfaces, described rib 42 is around the sidewall 331 of described magnetic bowl 33, and rib 42 can play the role of positioning to magnetic bowl 33.
In addition, form ante-chamber 101 between loam cake 11 and the vibrating diaphragm 21, acoustical generator 100 is provided with the side 10 of the direction of vibration that is parallel to vibrating diaphragm 21, also be provided with the louver 110 that is positioned at acoustical generator side 10 and is communicated with ante-chamber 101 between loam cake 11 and the basin frame 40, louver 110 is arranged in loam cake 11 and its bearing of trend perpendicular to the direction of vibration of vibrating diaphragm 21, thus so that acoustical generator 100 side sounding so just can be reserved more space to mobile phone screen.
